Kyrgyzstan and Tajikistan: the border is settled, the water is not

The Kyrgyz–Tajik border treaty of March 2025 is working as a border treaty. Pillars are going into the ground, checkpoints that were shut for four years are open and the two governments talk about trade targets rather than casualties. What the treaty has not yet shown is that it can carry the load that made the border lethal in the first place: the sharing of irrigation water in the upper Isfara valley during a dry summer. That is where attention should now go.

From signature to pillars

Presidents Sadyr Japarov and Emomali Rahmon signed the treaty in Bishkek on 13 March 2025, ending a delimitation process that began in December 2002. Both parliaments ratified it. The context was grim. The 2022 fighting killed more than 100 people and forced more than 100,000 Kyrgyz citizens from their homes, according to the CACI Analyst.

Physical demarcation has moved faster than most comparable processes in the region. On 14 July 2026 the two sides jointly installed the first four pillars at the point where their border meets Uzbekistan's, Kabar reported. They plan 1,954 in all. Joint field surveys have covered about 416 km. Orif Khojazoda, who chairs Tajikistan's State Committee for Land Management and Geodesy, said in July that nearly 90 per cent of engineering work was done, including fencing on about 300 km, and that the hardest section in Sughd province was complete. He expects demarcation to finish in 2027.

One detail deserves a note. Kabar gives the border's length as 1,008.14 km, which Tajik officials also use; the 972 km figure widely quoted at signing, including by the CACI Analyst, is shorter. The difference probably reflects how the line was measured rather than any change in the settlement, but neither side has explained it publicly, and it is worth watching as pillars go in.

What changed for people on the line

The Kyzyl-Bel–Guliston and Kairagach–Madaniyat crossings reopened on the day the treaty was signed, after almost four years of closure. For villages in Batken and Sughd, where families, markets and pastures straddle the line, that matters more than any trade statistic.

The settlement also moved people and property. In April 2026 Kyrgyzstan's cabinet transferred land and buildings received from Tajikistan into state ownership, to be distributed in the Batken and Leylek districts to residents who lost homes under the agreement or whose property was demolished for border infrastructure, The Times of Central Asia reported. Kyrgyzstan has also started building barriers along the new line. The CACI Analyst recorded protests by some Batken residents about territory ceded without adequate consultation. How fairly the compensation is handled will shape local consent more than the treaty text.

Trade is back, but only to where it was

The trade rebound is real in percentage terms and small in absolute ones. Asia-Plus puts bilateral turnover at $33.1m in 2025, up from $12.2m in 2024. The Kyrgyz Export Center's director, Urmat Takirov, cited $30–36m for the first seven to eight months after reopening, a range that does not sit neatly with a calendar-year figure. The differences come from whose customs data is used and which months are counted, and neither government publishes a reconciled series. On any of these measures, 2025 trade was roughly where it stood in 2020, at $37m. The rebound restored a relationship that the closure had cut to a third; it did not create a new one.

The composition explains the ceiling. Tajikistan sells table grapes, cotton products and electricity; Kyrgyzstan sells lignite, oil products and pasta. The two economies produce similar things, border markets that once traded twice a week remain closed, and there has been no recorded investment between them since 2022. The presidents' goal of $500m in annual trade is about fifteen times the 2025 figure. Treat it as a statement of intent rather than a forecast.

Water is the unfinished part

The 2021 fighting started at the Golovnoi intake on the river the Kyrgyz call Ak-Suu and the Tajiks call Isfara. Tajikistan had argued the structure lay entirely on its territory; Kyrgyzstan disputed that. The 2025 settlement split the intake. Kyrgyzstan's security chief, Kamchybek Tashiyev, said in February 2025 that the three sluices had been divided 'one and a half each', with Tajikistan transferring 750 hectares to Kyrgyzstan in compensation. He referred to agreements on how the water itself would be divided but gave no figures.

That gap is the treaty's weak point. Owning half a gate is not the same as a rule on how much water passes through it in July, when demand peaks on both banks and the river is at its lowest. Gates can be opened or closed by whoever controls them; a volume rule needs agreed measurement, shared data and someone both sides accept to settle a dispute on the day. The only published reference point is a Soviet-era protocol from 1980 that allocated the Isfara's flow at 55 per cent to Tajikistan, 37 per cent to Kyrgyzstan and 8 per cent to Uzbekistan. Whether that formula still applies, and who measures it, has not been set out publicly. We found no published volume schedule under the 2025 agreements.

This year tested the gap without breaking it. On 29 September AKIpress reported wells being drilled in the Sumbula municipality of Batken's Leylek district to make up for a shortage of irrigation water. There were no reports of clashes at Golovnoi. That is a genuine achievement, and it suggests that communities and border services now have channels they lacked in 2021. It does not prove that the arrangement would survive a sharper shortage, or a season in which one side's farmers believe the other has taken more than its share and there is no joint gauge to settle the argument.

What to watch

Three things will show whether the settlement is durable. First, whether the two governments publish, or at least agree between their water agencies, a seasonal water schedule for the Isfara intakes with joint measurement. Second, whether the reopened border markets and the promised compensation in Batken and Leylek actually materialise, since local grievances are what turned water disputes into armed clashes before. Third, whether demarcation is completed in 2027 as planned without new disputes over individual plots. Trade targets matter less. A quiet irrigation season in a dry year is the better measure of success, and 2026 has passed that test once.
